(2) Now implement a convert_words() function, which has a list of words as a parameter, and returns a list of words all in lower case. Then extend your program to prompt the user as before, but this time also convert the words to lower case using convert_words(), sort them, and then print the list of lower case words again using print_words(). See the following: es ai Enter a sentence (without punctuation): This Is a Sentence That Repeats this is a sentence that repeats but has different words with Capitals Sorted list of words: Capitals Is Repeats Sentence That This a a but different has is repeats sentence that this with words Sorted list of words in lower case: a a but capitals different has is is repeats repeats sentence sentence that that this this with words
(6) Implement the ReplaceExclamation() function. ReplaceExclamation() has a string parameter and updates the string by replacing each '!' character in the string with a '.' character. ReplaceExclamation() DOES NOT output the string. Call ReplaceExclamation() in the PrintMenu() function, and then output the edited string. Ex. Edited text: We'll continue our quest in space.

Use the catalog list ofdictionaries in the provided catalog.py file to look up a variety of information about abookstore catalog. Hint: To access the file from within your solution, you should add an import catalog call tothe top of your Python file.by calling catalog. catalog. this is the catalog file: csci = {"abbreviation":"CSCI", "department":"Computer Science","classes": [{"number": "1133", "textbook": "Programming in Python", "price":60.00},{"number": "3081W", "textbook": "UML Distilled", "price":45.00},{"number": "4041", "textbook": "Introduction to Algorithms", "price":70.00},{"number": "4511W", "textbook": "Artificial Intelligence", "price": 159.99},{"number": "5511", "textbook": "Artificial Intelligence", "price": 159.99}]} chen = {"abbreviation":"CHEN", "department":"Chemical Engineering","classes": [{"number": "3101",…
Python has the following syntax: In order to print each item in a list, create a function called Multiply2 that multiplies the list's elements by 2. For instance: mylist=[1,2,3,4] Multiply2(mylist) prints: 2.2.4.6.8 The function requires just one argument, which is the list on which the operation is to be done. After invoking the method, it's fine if the list is empty.

In this problem, you have available to you a working version of the function round_up described in part (a). It is located in a module named foo. Using the given round_up function, write a function round_up_all that takes a list of integers and MODIFIES the list so that each number is replaced by the result of calling round_up_ on that number. For example, if you run the code, 1st = [43, 137, 99, 501, 300, 275] round_up_all(1st) print(1st) the list would contain the values [100, 200, 100, 600, 300, 300] Do not re-implement the round_up function, just import the food module and use it. Here is the code for the round_up function that can be imported using foo: def round_up(num): if num % 100 == 0 : #if number is complete divisible return num #return orginal num else: return num + (100-(num % 100)) #else add 100-remainder to num, if __name__ == '__main__': print(round_up(234)) print(round_up(465)) print(round_up(400)) print(round_up(89))
PYTHON!!! Write a function that will filter course grades that are stored in a list, creating and returning a new list. Your implementation must have the following rules: - The function must accept two (and only two) parameters: The first is: the maximum integer value for any grade to remain in the list (any value above the maximum will be filtered and removed from the list). The second is: the list of grades (you can assume the list contains only integer values) - The function must return a new list and not modify the existing list. - The function must use a list comprehension to filter the existing list and create the new list that is returned. - DO NOT USE THE: built-in-"filter" function.

In c++, please! Thank you! Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size). Complete main() to read in a list of up to 10 positive integers (ending in -1) and then call the SelectionSortDescendTrace() function. If the input is: 20 10 30 40 -1 then the output is: 40 10 30 20 40 30 10 20 40 30 20 10 The following code is given: #include <iostream> using namespace std; // TODO: Write a void function SelectionSortDescendTrace() that takes// an integer array and the number of elements in the array as arguments,// and sorts the array into descending order.void SelectionSortDescendTrace(int numbers [], int numElements) { } int main() { int input, i = 0; int numElements = 0; int numbers [10]; // TODO: Read in a list of up to 10 positive…
Hello, I have an assignment in the python program. Professor gives me a text like this: January.txt 217283921200.5619.18,29.15,78.75,212.10100,20,410.29 The first line is an account number, the second line is the beginning balance, the third line is withdrawn and the last line is deposits. How can I separate every single line to read them. Can I use the loop function? Below is the assignment direction. Thank you very much ___________________________________________________________ Complete the following program: a) Read in and store the data from the file called “January.txt”. This file includes the customer’s account number, beginning balance, withdrawals, and deposits. (In that order) Note: Make sure you look at the file before you begin the project! b) Prompt the user for his/her name and age. c) Convert the customer’s name to a username that consists of the first letter of the first name, the first 5 digits of last name, and the customer’s age.(All letters should be lowercase)…
